IEC 62368-1 Figure V.3 Blunt Probe

This IEC 62368-1 Figure V.3 Blunt Probe is a specialized safety tool designed to test audio/video, information, and communication technology (AV/ICT) equipment. It features a blunt, rigid stainless steel tip that mimics accidental contact with equipment openings—critical for verifying hazardous live or mechanical parts remain inaccessible. Paired with a lightweight insulating nylon handle for safe grip, it strictly follows the dimensional and functional requirements of IEC 62368-1. Durable and easy to maneuver, it ensures consistent compliance checks, making it essential for manufacturers and labs to meet global AV/ICT safety standards and prevent end-user injuries.

Standards:

Specifications:
Probe Type: IEC 62368-1 Figure V.3 Blunt Probe (for AV/ICT equipment safety testing)
Probe Material: Stainless steel (rigid, corrosion-resistant, maintains dimensional stability)
Handle Material: Nylon (insulating, non-slip, heat-resistant for safe operation)
Key Dimensions:
– Blunt Tip Diameter: 5.0 mm ± 0.1 mm
– Effective Probe Length: 70 mm ± 0.2 mm
– Handle Length: 110 mm ± 0.5 mm
– Total Length: 180 mm ± 0.5 mm
– Tip Radius: 2.5 mm ± 0.05 mm (blunt design to avoid enclosure damage)
Applied Force: No appreciable force (mimics light, accidental user contact with AV/ICT equipment)
Core Function: Verifies inaccessibility of hazardous live/mechanical parts in AV/ICT equipment per IEC/UL 62368-1

Test Procedures:
1. Inspect the probe for damage (e.g., bent tip, cracked handle) to ensure testing accuracy.
2. Power on the AV/ICT equipment and let it reach normal operating mode.
3. Hold the nylon handle and align the blunt tip with equipment openings (e.g., vents, port gaps).
4. Gently guide the probe toward internal hazardous parts (e.g., live circuits, small moving components).
5. Check if the probe touches any dangerous elements.
6. Record whether the equipment meets safety requirements (pass/fail).

Applications:
1. Safety testing of smart TVs and streaming devices (per IEC 62368-1:2022 Figure V.3).
2. Compliance checks for laptops and wireless routers to block access to hazardous parts (UL 62368-1:2023).
3. Verification of office AV equipment (e.g., projectors, conference speakers) for mechanical/electrical hazard protection.
4. Quality control for portable audio devices (e.g., Bluetooth headphones, portable speakers) during manufacturing.
5. Post-production safety audits of ICT equipment (e.g., desktop computers, network switches) for global market compliance.
